2-氨基-5-氯二苯甲酮 | 2-Amino-5-chlorobenzophenone | 719-59-5 | C13H10ClNO | 231.681 |
Reaction between 2-(2′,2′-bis-carboethoxyvinylamino)-benzophenones, resulting from the condensation of 2-aminobenzophenones with diethyl ethoxymethylenemalonate, and hydrazine hydrate yields 5-hydroxy-5-phenyl-1,3,4-3H-4,5-dihydrobenzotriazepines or their double bond isomers. These products on acetylation afford O,N,N-triacetates, which on treatment with ammonia are transformed into 4-phenylquinazolines. Structure proof of these substances is reported.
